In a context of capital expansion towards the Andes Mountains, the decree 225/17 ordered the sale of properties considered idle or unused. Among them was a land that since 1901 has been administered by the National Army, called Campo Los Andes. It is located in the Valle de Uco (Central-West Argentina), epicenter of the tourism-winegrowing development of high range wines. To stop this sale, its civil dwellers together with very diverse social actors –among them, members of citizen assemblies, political parties, peasant and environmental organizations and different professionals– carried out collective actions in defense of this territory and of the national sovereignty.
